6 GB Standard Memory Amount for GeForce Titan

@ 2013/02/05

NVIDIA's next high-end graphics card, the GeForce "Titan" 780, is shaping up to be a dreadnought of sorts. It reportedly ships with 6 GB of GDDR5 memory as its standard amount. It's known from GK110 block diagrams released alongside the Tesla K20X GPU compute accelerator, that the chip features a 384-bit wide memory interface. With 4 Gbit memory chips still eluding the mainstream, it's quite likely that NVIDIA could cram twenty four 2 Gbit chips to total up 6,144 MB, and hence the chips could be spread on either sides of the PCB, and the back-plate could make a comeback on NVIDIA's single-GPU lineup.

On its Radeon HD 7900 series single-GPU graphics cards based on the "Tahiti" silicon (which features the same memory bus width), AMD used 3 GB as the standard amount; while 2 GB is standard for the GeForce GTX 680; although non-reference design 4 GB and 6 GB variants of the GTX 680 and HD 7970, respectively, are quite common. SweClockers also learned that NVIDIA preparing to price the new card in the neighborhood of $899.
